Techniques for traffic diversion in software defined networks for mitigating denial of service attacks

摘要

A method and system for mitigating of cyber-attacks in a software defined network (SDN) are presented. The method comprises operating a central controller and the SDN in a peace mode; monitoring traffic addressed to at least one destination server to detect at least an attack performed against the at least one destination server; switching an operation of the central controller to an attack mode, upon detection of an attack against the at least one destination server; and instructing, by the central controller, network elements of the SDN to divert all suspicious incoming traffic addressed to the at least one destination server to a security server, thereby mitigating the detected attack.
